Abstract

The Turnoff Delay Accessory is a in-line circuitry able radio battery is always charged and the vehicle module for use in supply cabling of lgnition switch battery is not discharged. Another way is to connect controlled vehicular battery chargers (VA). Portable the wire to the ignition switch. For Utility truck radio batteries are charged by the vehicular charger. applications, the vehicle is off for long periods of The VA can be wired two ways. One is with the time and the VA will not discharge the vehicle bat- ignition switch wire connected directly to the vehi- tery this way. However, ifthe vehicle is used for short cle battery positive causing the charger to be always trips to work sites as shown in the figure below, the on. For vehicles always in use, this assures the port- battery may not be fully charged.
